Starting with release 21, xemacs does not come with lisp packages
any more. Instead, they are distributed separately from the main
sources.
This port provides a set of the libs category packages provided by
xemacs.org(www.xemacs.org) except for basic and mule-basic packages(those are
editors/xemacs-packages and editors/xemacs-mule-basic-packages ports
respectively).
To install other categories' packages, use editors/xemacs-*-packages
ports/packages.

Use ${ECHO_CMD} instead of ${ECHO} where you mean the echo command; the ECHO
macro is set to "echo" by default, but it is set to "true" if make(1) is
invoked with the -s option while ECHO_CMD is always set to the echo command.

Added ${MASTER_SITE_LOCAL} to all editors/xemacs-*packages/Makefile in order
to fetch obsolete xemacs' packages. Current all xemacs' packages needed to
make have already copied to freefall:~kiri/public_distfiles. PR ports/23171
would be solved with this commit.
